The root hairs absorb from soil

Options

A. percolating water
B. capillary water
C. hygroscopic water surrounding each soil particle
D. water from the water table

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks what type of water root hairs absorb from the soil. Root hairs are specialized structures on plant roots that are primarily responsible for the absorption of water and minerals.

2. **Identifying the Options**: The options provided are:
- a) Percolating water
- b) Capillary water
- c) Hygroscopic water
- d) Water from the water table

3. **Analyzing Each Option**:
- **Percolating Water**: This refers to water that is found beneath the soil and is not accessible to root hairs. Therefore, this option is incorrect.
- **Capillary Water**: This is the water held in the micropores of the soil and is available to plants. It is the water that root hairs can absorb, making this option a strong candidate.
- **Hygroscopic Water**: This water is tightly bound to soil particles and is not available for absorption by plants. Thus, this option is also incorrect.
- **Water from the Water Table**: This water is located below the capillary line and is not accessible to root hairs. Therefore, this option is incorrect as well.

4. **Conclusion**: After analyzing all the options, the only type of water that root hairs can absorb from the soil is **capillary water**.

5. **Final Answer**: The correct answer is **b) Capillary water**.
